While it is good to know some people are following this post, I think it would be best to keep the clutter down if possible. I am hoping that I can get it working enough that others might be able to start assisting me at some point and it is easier to read if there is less clutter. I do appreciate the cheering on (it is alot of work so far), but this thread isn't really the place for it. Besides, until it is at least somewhat usable, there isn't much to cheer about. There is a good chance that we may never have enough info to get SoF fully functional. I am trying to stay positive about it though lol.
I have already learned a ton over the past couple of weeks just playing with the different sources I have available to me to get them all frankenstiened into something that will at least let us log all of the way in. If I could read the assembly code better, it may eventually be possible to pull everything we need straight from there, but I am still a good ways from being able to understand it enough to do that.
Currently, I am trying to understand the item serialization code. I have the full itemlist for SoF, and I think it should be very close to accurate. But, until I know how to set the serialization up so that it works with my new list, I can't load items. Other than that, I already have a large amount of the bare minimum opcodes needed to log in. There are only a few more I need to have a complete list. Here is what I have so far:
Code:
Opcode Name=Titanium Op - SoF Op
OP_SendLoginInfo=0x4dd0 - 0x6c3c V
OP_GuildsList=0x6957 - 0x04FB V
OP_LogServer=0x0fa6 - 0x129A V
OP_ApproveWorld=0x3c25 - 0x7FC0 V
OP_EnterWorld=0x7cba - 0x1340 V
OP_PostEnterWorld=0x52A4 - 0x1AEE V
OP_ExpansionInfo=0x04ec - 0x0A1B V
OP_SendCharInfo=0x4513 - 0x6040 V
OP_World_Client_CRC1=0x5072 - 0x7a9e V
OP_World_Client_CRC2=0x5b18 - 0x3795 V
- 0x22cf - size 2056 - Some new CRC from SoF. This shouldn't be required to use at all.
- 0x43ba - size 2056 - Some new CRC from SoF. This shouldn't be required to use at all.
OP_AckPacket=0x7752 - 0x4D38 V
OP_WorldClientReady=0x5e99 - 2EBD V
0x58FB - size 8 - the Auto-AFK opcode - This isn't in Titanium opcodes, but does exist. Not required though.
Log into a zone:

OP_TGB=0x0c11 - 0x0137 V?
OP_ClientUpdate=0x14cb - 0x5Cf3 V?
OP_FloatListThing=0x6a1b - I don't have this yet, but it comes from the client and should be able to get it from the tail once I can get in game with SoF
The V means it has been verified either from the client, or from IDA or both. This is about 95% sure to be accurate. The V? means I verified it from IDA, but the code isn't an exact match, so I am only 50-75% sure it is accurate. The ??? means I was either unable to find it at all in IDA, or that I found it and it doesn't look like a match to me, they are likely to be wrong.
I think if we can get all of those, I may have enough opcodes correct that we can at least log in a naked character all of the way. Once the item serialization is done for SoF, we should be able to login geared characters as well. I think the main opcode I need to be accurate now is the doorspawn opcode. I think that also sends objects in the zone and seems to be where the naked test character is getting hung up at.
Like I said, as soon as I can get any character logged in all of the way, I will submit my changes to the SVN so others can assist with it if they want. What I will probably do is set it so that the Anniversary files (that I am using for getting SoF to work currently), will not be used by default on new builds. It would be disabled by a simple define and could be easily enabled by anyone who wanted to mess with it. I will post how to enable it if I can get to that point. It will just mean a simple 1 line code change to enable it (uncommenting a #define). The reason to leave it disabled is so you don't have players trying to use SoF and crashing zones if there are issues with it that cause crashes.

Found them: showeq/src/everquest.h. Maybe some of the later changes to the structs might provide some insight on what the unknown values may be... |
If we're still looking for newer structs (after 2006), we can peek into the SEQ SVN. Specifically, SoF structs should be in Rev 686 (11/5/2007), Rev 688 (11/21/2007), or Rev 690 (11/27/2007). Since, according to Wikipedia, it was released on 11/13/2007, we'll probably want to look at Rev 688. |

Ya, I have been using all of those to get as far as I have :P They have been very useful.
Even though SoF was released on 11/13/07, it was actually built on 9/7/07 (according to the EQ Debug Logs). So, anything from 9/7/07 to around the beginning of 2008 is probably useful. They may have patched in some of the SoF stuff to live before it actually came out, so the structures and stuff may have already been there for the most part. The main thing that would have changed alot are the opcodes. Unfortunately, most of the opcodes in SEQ weren't updated until after December, so many of them aren't correct.
I am thinking about trying a current version of SEQ and running a trial live account just to see if I can find 100% accurate structures that can be used to help getting SoF to work. I am betting that the current live structs are probably closer to SoF than the Titanium ones are.
If anyone has packet collects from right around the time that SoF was released (preferrably from SEQ if possible), I would love to get a copy of them. I think that would help alot once I knew what I was looking at. But, I am not holding my breath to get them, because I doubt anyone has still them.
I am not really sure what it is for, but a code obfuscater was added to SEQ around the time that SoF came out. From looking at the comments around the code for it, it appears to be used for pulling opcodes directly from the assembly code of the eqgame.exe. I have no idea how it is actually used though, or if I am just misunderstanding what it does. I have seen comments about it on the SEQ forums that seem to say something about opcodes changing from time to time when you zone or log on other characters/servers. I guess it is some kind of simple encryption or something. But, it seems that the new obfuscate can pull an opcode table from the exe file. If that is true, maybe we can use it on Titanium, and then on SoF and compare the 2 tables and compare the conf files for known opcodes and match them up. Here is a link to the obfuscate getting added to SEQ SVN:

I moved this to the development section, because it seems more appropriate.

I figured out where it is currently breaking when it is trying to log in. It seems that the opcode OP_SendExpZonein=0x3703 is where the problem is. This is the last opcode that the client receives before it stops responding. I also verified that by removing this opcode from Titanium it will fail at the exact same point according to the EQ Debug Logs.
Code:
DoMainLoop: just before first while(!EverQuest.ReceievedWorldObjects).
Actually, in Titanium, the log entry is slightly different, but it is the same thing just renamed:
Code:
DoMainLoop: just before first while(!ReadyEnterWorld).
My guess is that this opcode now needs to be encoded like many of the other important ones. And since it isn't being encoded, it isn't recognizing it, so it is failing. I am 99% sure that I have the correct opcode set for it.
Looking at the place where it is failing, here is the Assembly code for it:

And, from client_packet.cpp, here is the code that handles that opcode:
Code:
void Client::Handle_Connect_OP_SendExpZonein(const EQApplicationPacket *app)
{
//////////////////////////////////////////////////////
// Spawn Appearance Packet
EQApplicationPacket* outapp = new EQApplicationPacket(OP_SpawnAppearance, sizeof(SpawnAppearance_Struct));
SpawnAppearance_Struct* sa = (SpawnAppearance_Struct*)outapp->pBuffer;
sa->type = AT_SpawnID; // Is 0x10 used to set the player id?
sa->parameter = GetID(); // Four bytes for this parameter...
outapp->priority = 6;
QueuePacket(outapp);
safe_delete(outapp);
// Inform the world about the client
outapp = new EQApplicationPacket();
CreateSpawnPacket(outapp);
outapp->priority = 6;
if (!GetHideMe()) entity_list.QueueClients(this, outapp, true);
safe_delete(outapp);
if(GetPVP()) //force a PVP update until we fix the spawn struct
SendAppearancePacket(AT_PVP, GetPVP(), true, false);
//Send AA Exp packet:
if(GetLevel() >= 51)
SendAAStats();
// Send exp packets
outapp = new EQApplicationPacket(OP_ExpUpdate, sizeof(ExpUpdate_Struct));
ExpUpdate_Struct* eu = (ExpUpdate_Struct*)outapp->pBuffer;
int32 tmpxp1 = GetEXPForLevel(GetLevel()+1);
int32 tmpxp2 = GetEXPForLevel(GetLevel());
// Quag: crash bug fix... Divide by zero when tmpxp1 and 2 equalled each other, most likely the error case from GetEXPForLevel() (invalid class, etc)
if (tmpxp1 != tmpxp2 && tmpxp1 != 0xFFFFFFFF && tmpxp2 != 0xFFFFFFFF) {
float tmpxp = (float) ( (float) m_pp.exp-tmpxp2 ) / ( (float) tmpxp1-tmpxp2 );
eu->exp = (uint32)(330.0f * tmpxp);
outapp->priority = 6;
QueuePacket(outapp);
}
safe_delete(outapp);
if(GetLevel() >= 51)
SendAATimers();
outapp = new EQApplicationPacket(OP_SendExpZonein, 0);
QueuePacket(outapp);
safe_delete(outapp);
outapp = new EQApplicationPacket(OP_RaidUpdate, sizeof(ZoneInSendName_Struct));
ZoneInSendName_Struct* zonesendname=(ZoneInSendName_Struct*)outapp->pBuffer;
strcpy(zonesendname->name,m_pp.name);
strcpy(zonesendname->name2,m_pp.name);
zonesendname->unknown0=0x0A;
QueuePacket(outapp);
safe_delete(outapp);
/* this is actually the guild MOTD
outapp = new EQApplicationPacket(OP_ZoneInSendName2, sizeof(ZoneInSendName_Struct2));

strcpy(zonesendname2->name,m_pp.name);
QueuePacket(outapp);
safe_delete(outapp);*/
if(IsInAGuild()) {
SendGuildMembers();
}
//No idea why live sends this if even were not in a guild
SendGuildMOTD();
return;
}
So, either the opcode needs to be encoded, or this handling code needs to be changed. I am guessing the opcode needs to be encoded, because the jump is looking for anything that isn't 0, so I would think that it is just making sure it got something for it. And, if it isn't encoded and is supposed to be, maybe it shows up as 0. But, if it doesn't need to be encoded, I don't know why it would be 0.
I will mess with it and see if I can figure out how to get that opcode encoded, but I don't really know how that will work, since the only opcodes I see currently getting encoded already have structures tied to them, but I don't see one for SendExpZonein. Unless maybe it is named differently.
At least I know where it is failing now, so I should be able to come up with something to move it to the next step. It should be getting pretty close now. I was able to find and verify more of the required opcodes for logging in over the past couple of days as well. Making some progress at least  |
